Re: [Discuss-gnuradio] ERROR DURING GR-GFDM INSTALLATION BLOCKS IN GNURADIO.

Hi Elkin - Reviewing the files "CMakeLists.txt" and "lib/CMakeLists.txt", it seems as though Volk is requested but not required, and then not used:

{{{

% find . -name CMakeLists.txt -exec grep -i volk {} +

./CMakeLists.txt:find_package(Volk "1.3")

}}}

Also, FFTW3f is used internally in the C++ code, but is not checked for or linked against. Those are pretty easy additions to those CMakeLists.txt files ... look at (for example, respectively of Volk and FFTW3f) gr-ieee802-15-4 and gr-iqbal. As already pointed out, you'll need to remove the "1.3" from the Volk check, since Volk API 1.3 isn't necessarily backward compatible with the 1.4 API; for the needs of gr-gfdm, either 1.3 or 1.4 seem to work. You also need the Python commpy package for testing. Hope this is useful. - MLD

Hi everybody, I am trying to install "gr-gfdm" downloaded from GitHub, I follow step by step installation process but when I execute the line command "make test" got the next errors.

For show the cause of error of an specific item (for example "5 - qa_simple_modulator_cc") I trying with the command line "ctest -V -R qa_simple_modulator_cc" and the result is the next:

Then, How do I for solve the errors during gr-gfdm installation?

PD: I have installed previously the requeriments for gr-gfdm (GNU Radio OOT and PyGFDM items).

Thank you all.
